Thanks to you Randy and Dale.

CONFESSION:    I am a dunce, but I do not see what you and Dale previously 
sent about Great Circle Mapper.  Inserting MY coordinates and a given 
distance only displays a circle of that given distance with me as the 
center.  Everything outside that distance surely is not in the shadow zone. 
Perhaps, I do not know what the magic distance should be?

  Here is a link to a great circle mapper.  You can put in coordinates and 
generate a world map with your location and concentric cirles at any desired 
distance.  I have done mine for each 10 degrees out to the shadow zone and 
then again from the far side of shadow zone.  I just set this image as 
wallpaper for my desktop for quick reference.
